  However, in the head mounted display device described in Patent Document 1, the user cannot observe the image displayed on the display screen while the display screen is moved to a position other than in front of the eyes. Therefore, in order not to generate an unviewed section, the user has to stop the image by performing a pause operation each time. Also, if you want to keep listening to the voice, there is a possibility that you will be forced to watch a small piece of music by entering a pause.

  Therefore, an object of the present invention is to provide a technique that allows the display screen to move to a position other than the user's eyes and efficiently check the image of the section that is not viewed by the user.

In order to solve the above-described problems, the head-mounted display device of the present invention sets a non-viewing section of a display unit and an image data to be displayed on the display unit from the position of the display unit. Control means for performing notification of being performed and reproduction of the unviewed section.

  As described above, according to the head mounted display device of the present invention, it is possible to provide a technique that allows a user to efficiently check an unviewed part.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 shows a head mounted display device (hereinafter abbreviated as HMD) 1 according to a first embodiment of the present invention. FIG. 1 is a perspective view of the HMD 1 according to the first embodiment of the present invention.

  As shown in the figure, the HMD 1 according to the present embodiment includes a head wearing band 11, an audio output unit 12, a housing 13, a support unit 14, an arm unit 15, a display unit 16, and an operation unit 17. It is equipped with.

  The head mounting band 11 is formed in a curved shape so that both ends thereof face each other. The head wearing band 11 is made of a material having elasticity, and the HMD 1 is attached to the user's head by pressing a speaker, which will be described later, toward the inside of the user's head when the head wearing band 11 is worn on the user's head. It can be detachably attached to the head.

  Cases 13 </ b> A and 13 </ b> B (in the case where they are not distinguished from each other) are connected to both longitudinal ends of the head mounting band 11. A speaker 12A is connected to the housing 13A, and a speaker 12B is connected to the housing 13B. Further, power is supplied from the power source (not shown) built in the housing 13B and the control device 10 to each part and the power source in the head wearing band 11 and the power source. A power line or the like is wired.

  The sound output unit 12 converts the sound signal into sound and outputs the sound. Specifically, the audio output unit 12 according to the present embodiment includes speakers 12A and 12B, which are so-called headphones speakers used by being applied to both ears of the user. In FIG. 1, the right speaker 12A is for the left ear, and the left speaker 12B is for the right ear. These left and right distinctions may be arbitrarily determined by the user's operation, or may be switched depending on whether the display unit 16 is viewed with the right eye or the left eye. In addition, a power line for supplying power from the power source and a sound signal line for supplying a sound signal are wired to the sound output unit 12.

  The housing 13B incorporates a control device 10 and a power source. Furthermore, the HMD 1 according to the present embodiment has an operation unit 17 on the outer wall surface of the housing 13B opposite to the speaker 12B.

  Further, the housing 13A includes a power switch (not shown) that switches the power of the HMD 1 on and off on the outer wall surface opposite to the speaker 12A.

  The power source, the power switch, the control device 10, and the operation unit 17 may be arranged in any of the housings 13A and 13B, and the housings 13A and 13B are integrated with the speakers 12A and 12B, respectively. It is good also as a structure.

  The support portion 14 rotatably connects one end side of the arm portion 15 to the housing 13B. As shown in the figure, the user can move the display unit 16 to a position overlapping the head wearing band 11 by rotating the arm unit 15 around the support unit 14 as a rotation center. Further, the user can wear the HMD 1 so that the left and right of the speakers 12A and 12B are reversed, and use the arm unit 15 rotated 180 degrees so that the display unit 16 is disposed in front of the eyes. . That is, the user can place the display unit 16 in front of either the left or right eye.

  The arm unit 15 is arranged so that when the head mounting band 11 is mounted on the user's head, the display unit 16 attached to the other end side of the housing 13A is positioned in front of the user's eyes. Curved in the longitudinal direction. In addition, a power line for supplying power from the power source to the display unit 16 and an image signal line for supplying an image signal are wired.

  The display unit 16 is coupled to the tip of the arm unit 15 so as to be rotatable in the vertical and horizontal directions in accordance with the user's line of sight. The display unit 16 includes, for example, an LCD (Liquid Crystal Display) for displaying an image and an optical system for enlarging the displayed image, and displays the image based on the supplied image signal.

  The operation unit 17 includes a plurality of operation switches 171. The user can input instructions regarding functions related to the HMD 1, such as play, stop, fast forward, rewind, volume change, and other control processes, via the operation switch 171. An operation instruction input via these switches is transmitted to the control unit 101 via an input / output interface unit 104 (hereinafter referred to as I / F unit; see FIG. 2) described later.

  The HMD 1 further includes an angular velocity sensor and an acceleration sensor that detect direction information regarding the movement of the user's head as an angular velocity and acceleration as input means other than the operation unit 17, and performs processing corresponding to the detected angular velocity and acceleration. It is good also as a structure which performs.

  Next, the control apparatus 10 with which HMD1 concerning 1st embodiment of this invention is provided is demonstrated with reference to FIG. FIG. 2 is a block diagram illustrating a functional configuration of the HMD 1.

  As illustrated in FIG. 2, the control device 10 includes a control unit 101, a storage unit 102, an arm position detection unit 103, and an I / F unit 104.

  First, the arm position detection unit 103 will be described. The arm position detection unit 103 is mounted on the head when the display unit 16 rotates the use position (in front of the user's eyes) and the retraction position (near the user's head, that is, the support unit 14 rotates about the rotation center). A signal indicating that the band 11 and the display unit 16 are within a predetermined range including a position where the band 11 and the display unit 16 overlap most closely is output to the control unit 101.

  Specifically, the arm position detection unit 103 includes a proximity sensor 131. The proximity sensor 131 is, for example, a capacitive proximity sensor, and detects the approach of a surrounding object, and obtains a detection signal by replacing movement information and presence information of a detection target with an electrical signal.

  The proximity sensor 131 is attached to, for example, the arm unit 15 (or the display unit 16), and outputs a detection signal indicating the distance between the housing 13A (or the head-mounted band 11) and the arm unit 15. The arm position detection unit 103 receives a detection signal output from the proximity sensor 131. When the detection signal indicates that the arm unit 15 and the housing 13 </ b> A are separated from each other by a predetermined distance or more, the use position detection signal is output to the control unit 101. Further, when the detection signal output from the proximity sensor 131 is a detection signal indicating that the arm unit 15 and the housing 13A have approached within a predetermined distance, the arm position detection unit 103 proceeds to the control unit 101. A retraction position detection signal is output.

  In addition, the kind of sensor for detecting the position of the arm part 15 is not limited to the above. An inductive proximity sensor that detects the presence of metal, a switch that uses a magnetic direct current magnetic field, or the like may be used.

  Next, the control unit 101 will be described. The control unit 101 includes an information acquisition unit 111 that sets an unviewed section according to a detection signal from the arm position detection unit 103, an information notification unit 112 that displays a notification screen for notifying the user of an unviewed section, And an image playback unit 113 that receives an instruction from the user and plays back an unviewed section.

  When the information acquisition unit 111 receives the detection signal from the arm position detection unit 103, the information acquisition unit 111 sets an unviewed section related to the image content reproduced by the user.

  An unviewed section (segment) is a start position at which the arm unit 15 moves to the retracted position when the user is reproducing the image content, and the arm unit 15 returns from the retracted position to the use position. It is a section defined by the end position which is the timing. Such an unviewed section is referred to as a segment here for convenience.

  Specifically, when the information acquisition unit 111 receives a retraction position detection signal from the arm position detection unit 103 during reproduction of image content, the information acquisition unit 111 creates a new segment record in the segment data table (see FIG. 3).

  The segment data table is stored in the segment data storage area 121 of the storage unit 102, and a segment ID storage area 121a in which a segment ID for identifying each segment and each image content in which the segment is set is stored; An unviewed start position storage area 121b in which information indicating the start position of the segment is stored, an unviewed end position storage area 121c in which information indicating the end position of the segment is stored, and chapters set in advance in the image content And a chapter ID storage area 121d in which a chapter ID including each segment is registered.

  Here, the start position and the end position are reproduction times from the head position of the image. These may be any information as long as the information indicates a specific position of the image. For example, information such as the number of frames from the head position of the image may be stored.

  The information acquisition unit 111 assigns a segment ID for identifying each segment and each image content (for example, a file name) in which the segment is set, to the segment ID storage area 121a of the new segment record. Further, the playback time when the retracted position detection signal is received is stored in the unviewed start position storage area 121b.

  Further, when the information acquisition unit 111 receives the use position detection signal from the arm position detection unit 103, the information acquisition unit 111 stores the reproduction time when the retraction position detection signal is received in the unviewed end position storage area 121c of the latest segment record. . If a chapter is set for the playback image content, all the chapters including the segment of the segment record are detected from the metadata of the image content (see FIG. 4), and the chapter ID is set. And stored in the chapter ID storage area 121d.

  Metadata is information provided for each content stored in the content data storage area 122, and is composed of a plurality of pieces of specific information describing the content. For example, as shown in FIG. 4, it includes information such as the file name of the content, the number of chapters to be set, the start position and the end position of each chapter.

  Thereafter, the information acquisition unit 111 outputs a notification screen display request to the information notification unit 112.

  Next, the information notification unit 112 will be described. The information notification unit 112 displays a notification screen for notifying the user that the segment can be reproduced based on each segment record of the segment data table generated by the information acquisition unit 111.

  Specifically, when receiving a notification screen display request from the information acquisition unit 111, the information notification unit 112 generates a notification screen 810 (see FIG. 5) and causes the display unit 16 to display the notification screen 810. For example, a digest playback icon 811 for digest playback of each segment recorded in the segment data record and a segment playback icon 812 for playback of only each segment are displayed on the notification screen 810.

  The segment playback icon 812 may display the segment playback icon 812 for all of the segment records to be recorded, or may display only a predetermined number of records from the latest one. Further, the segment playback icon 812 may reduce the frame at the start position of the segment and display it as a thumbnail.

  Note that the notification screen 810 can be displayed in an overlapping manner, for example, while image content is reproduced by the image reproduction unit 113 and displayed on the display unit 16. Of course, the notification screen 810 can be displayed even when the image content is not reproduced.

  The user can instruct the image reproduction unit 113 to reproduce the digest and the segment corresponding to the displayed icon via the operation unit 17. Note that the user may input such a reproduction instruction by the operation of the head using an angular velocity sensor (not shown) or the like.

  Note that the information notification unit 212 may display / erase the notification screen 810 at regular intervals to repeatedly notify the user that an unviewed section exists. This timing may be configured to be arbitrarily set by the user, or the notification screen 810 may be displayed only when requested by the user.

  The image reproduction unit 113 reproduces the image content and the digest or segment of the image content corresponding to the reproduction icon in accordance with a reproduction instruction from the user.

  Specifically, when receiving a digest playback instruction, the image playback unit 113 performs digest playback of the image content according to a predetermined playback method.

  First, the image playback unit 113 refers to the segment ID storage area 121a of the segment data table and extracts a segment record related to the image content currently being played back. Then, the image playback unit 113 starts digest playback of the image content according to a predetermined playback method.

  As long as the predetermined playback method is a method in which the user can view a segment that is an unviewed section, the image content may be played back in any way. Reproduce.

  FIGS. 6A, 6 </ b> B, and 6 </ b> C are schematic diagrams illustrating an example of digest playback performed by the image playback unit 113.

  As one method of digest playback, the image playback unit 113 connects the segment records of specific image content and plays back as a digest image, as shown in FIG. Specifically, the image playback unit 113 arranges the segment records in chronological order, and starts playback of the image content from the playback time (start position) stored in the unviewed start position storage area 121b of the first segment record. When the playback time (end position) stored in the unviewed end position storage area 121c of the segment record is reached, the playback time (start position) stored in the unviewed start position storage area 121b of the next segment record is reached. Jump. By repeating this until the end position of the last segment record, the image reproduction unit 113 reproduces only the image in the unviewed section.

  As another digest reproduction method, as shown in FIG. 6B, the image reproduction unit 113 connects segment records of specific image contents at a predetermined position before and after the segment records and reproduces them as a digest image. Specifically, the image playback unit 113 arranges the segment records in chronological order, and sets a position (for example, 3 seconds before) a predetermined time before the playback time stored in the unviewed start position storage area 121b of each segment record. A position after a predetermined time (for example, after 3 seconds) from the playback time stored in the start position and the unviewed end position storage area 121c of each segment record is assumed as the end position. Then, by connecting the start position and the end position, the image reproduction unit 113 reproduces the unviewed section and the areas before and after it.

  As a further digest reproduction method, the image reproduction unit 113 reproduces a specific image content as a digest image by connecting chapters including segments as shown in FIG. 6C. Specifically, the image playback unit 113 searches the metadata of the image content for the chapter ID stored in the chapter ID storage area 121d of each segment record, and acquires the playback time of the start position and end position of each chapter. Then, by connecting the start position and the end position in chronological order, the image reproduction unit 113 reproduces the unviewed section for each chapter.

  Note that, when receiving a segment playback instruction, the image playback unit 113 starts playback of the segment. Similarly, the segment may be reproduced by any reproduction method, such as only the segment, the segment and its surrounding areas, and the chapter including the segment.

  In addition, all segment records in the segment data table are deleted after the digest and the segment have been viewed. Furthermore, when a part that has not been viewed remains, the start position and end position of the segment are updated for that part, and a new segment is set. Note that the user can arbitrarily set such deletion / update.

  Further, the image reproduction unit 113 may be configured to generate digest and segment image data and reproduce the image data. Of course, any generation method can be used for generation of image data.

  The I / F unit 104 connects the audio output unit 12, the display unit 16, and the operation unit 17 to the control device 10. In addition, as a general-purpose bus that connects the HMD 1 and an external device so as to be able to transfer data, a terminal conforming to a standard such as USB (Universal Serial Bus) or IEEE1394 is provided.

  Here, the hardware configuration of the HMD 1 will be described. FIG. 10 is a block diagram showing an electrical configuration of the HMD 1.

  As shown in FIG. 10, the HMD 1 stores a CPU (Central Processing Unit) 81 that controls each device, a memory 82 that stores various data in a rewritable manner, various programs, data generated by the programs, and the like. A nonvolatile auxiliary memory 83, an LCD 84, a speaker 12, and an I / F unit 104 that connects each device to the CPU 81. The control unit 101 can be realized, for example, by reading a predetermined program stored in the auxiliary memory 83 into the memory 82 and executing it by the CPU 81.

  Next, processing executed by the information acquisition unit 111 will be described in detail with reference to FIG. FIG. 7 is a flowchart illustrating a process in which the information acquisition unit 111 according to the first embodiment records an unviewed section. The information acquisition unit 111 starts this flow when the reproduction of the image content is started.

  The information acquisition unit 111 first detects reception of a retracted position detection signal from the arm position detection unit 103 (S11). When the retreat position detection signal is received (YES in S11), the process proceeds to S12.

  When receiving the retraction position detection signal (YES in S11), the information acquisition unit 111 creates a new segment record in the segment data table and defines its start position (S12). Specifically, the information acquisition unit 111 registers the segment ID in the segment ID storage area 121a, and stores the playback time when the save position detection signal is received in the unviewed start position storage area 121b (S12).

  Next, the information acquisition unit 111 detects reception of a use position detection signal from the arm position detection unit 103 (S13). When the use position detection signal is received (YES in S13), the process proceeds to S14.

  When receiving the use position detection signal (YES in S13), the information acquisition unit 111 defines the end position of the segment (S14). Specifically, the information acquisition unit 111 stores the reproduction time when the save position detection signal is received in the unviewed end position storage area 121c of the latest segment record. When chapters are set in the playback image content, all chapters including the segment of the segment record are detected, and the chapter IDs are stored in the chapter ID storage area 121d.

  Note that the information acquisition unit 111 ends the flow when the end of the currently reproduced image content is detected.

  According to such a configuration, the user can check an unviewed part without replaying the image data from the beginning. Moreover, since the unviewed part can be viewed as a digest, it is possible to efficiently view only the unviewed part.

  Next, a second embodiment of the present invention will be described. HMD2 which is 2nd embodiment demonstrates the matter relevant to the point different compared with 1st embodiment below, referring FIG. 8 and FIG.

  FIG. 8 shows a content distribution system according to the second embodiment of the present invention. As shown in the figure, the content distribution system includes a server 3 that distributes content and an HMD 2 that receives content distribution from the server 3 via a network 900.

  The network 900 is a public communication network including a telephone / mobile phone network and the Internet, and the HMD 2 is connected to the network 900 wirelessly and by wire. Of course, radio waves may be transmitted and received via a base station (not shown).

  Each segment may be directly added to the content data without being managed by the segment data table. For example, the segment can be directly registered as a new chapter in the metadata, and the segment can be called by the chapter. As a result, the user can view only the unviewed section by executing playback or skipping in units of chapters.

  Hereinafter, processing executed by each device of the content distribution system will be described with reference to FIG. FIG. 9 is a time chart showing an operation example of each device of the content distribution system according to the second embodiment.

  The HMD 2 includes a control device 20, and the control device 20 includes a control unit 201, a storage unit 202, an arm position detection unit 103, and an I / F unit 104.

  The control unit 201 acquires a signal from the arm position detection unit 103 and outputs information of the signal to the server 3, and an information notification unit that notifies the user of a reproducible digest and segment 212 and a streaming reproduction unit 213 that reproduces image data distributed from the server 3.

  When the signal acquisition unit 211 receives a retraction position detection signal from the arm position detection unit 103 during reproduction of the image content, the retraction position detection including the reproduction time at which the signal is received by the server 3 via the I / F unit 104. Send information. When the signal acquisition unit 211 receives the use position detection signal from the arm position detection unit 103, the signal acquisition unit 211 transmits use position detection information including the reproduction time at which the signal is received to the server 3 via the I / F unit 104. At the same time, a segment list relating to the content being reproduced is requested.

  When receiving the segment list provided from the server 3, the information notification unit 212 generates a notification screen 810 as shown in FIG. 5 according to the segment list, similarly to the information notification unit 112 according to the first embodiment. To be displayed on the display unit 16.

  Note that the notification screen 810 can be displayed in an overlapping manner even while streaming type image content is played back by the streaming playback unit 213 and displayed on the display unit 16.

  The streaming reproduction unit 213 receives the image data distributed from the server 3 and reproduces it. Specifically, when receiving the streaming type image data distributed from the server 3, the streaming playback unit 213 decodes it according to a predetermined decoding method while storing it in the content data storage area 221 of the storage unit 202. Then, an image signal and an audio signal are generated and output to the display unit 16 and the audio output unit 12.

  When the streaming playback unit 213 receives a digest and segment playback instruction from the user via the operation unit 17, the streaming playback unit 213 outputs a digest and segment distribution request to the server 3.

  Returning to FIG. 8, the configuration of the server 3 will be described. The server 3 includes a control unit 301, a storage unit 302, and an I / F unit 303.

  The storage unit 302 includes a content database 321, an image data storage area 322, and a segment data storage area 323.

  The content database 321 stores in advance content data to be distributed to clients (here, users of HMD2). The content data is, for example, all digital data such as music, video, images, and documents.

  The image data storage area 322 stores digest image data and segment image data generated by an image generation unit 312 described later based on the segment data table.

  Similar to the segment data storage area 121 according to the first embodiment, the segment data storage area 323 stores a segment data table as shown in FIG.

  The I / F unit 303 provides an interface between the network 900 and each functional unit, and connects the server 3 to the HMD 2 through the network 900 so as to be able to transmit and receive data.

  Next, processing executed by the control unit 301 of the server 3 will be described with reference to FIG.

  The control unit 301 of the server 3 generates a digest and a segment image based on the information management unit 311 that defines the segment and the digest and segment distribution request from the HMD 2 based on the retraction position detection information and the use position detection information from the HMD 2 An image generation unit 312 that performs streaming distribution of image data according to a distribution request from the HMD 2.

  The information management unit 311 manages the segment data table for each customer. Specifically, when the information management unit 311 receives the retraction position detection information from the HMD 2, the information management unit 311 creates a new segment record in the segment data table, and sets each segment and each image content (for example, a file) The segment ID for identifying (name) is registered in the segment ID storage area 121a, and the reproduction time included in the save position detection information is stored in the unviewed start position storage area 121b.

  Further, when receiving the use position detection information from the HMD 2, the information management unit 311 stores the reproduction time included in the save position detection information in the unviewed end position storage area 121c of the latest segment record. When chapters are set in the playback image content, all chapters including the segment of the segment record are detected from the metadata, and the chapter IDs are stored in the chapter ID storage area 121d.

  Furthermore, when receiving the segment list request from the HMD 2, the information management unit 311 provides the segment list to the HMD 2. Specifically, the information management unit 311 inquires the HMD 2 about the file name of the image content being reproduced, extracts a segment record related to the image content from the segment data table, and transmits the segment record to the HMD 2 as a segment list.

  Upon receiving the digest and segment distribution request from the HMD 2, the image generation unit 312 generates digest image data and segment image data according to a predetermined generation method, stores the digest image data and segment image data in the image data storage area 322, and transmits the image to the streaming distribution unit 313. Request data delivery.

  As long as the predetermined generation method includes a segment that is an unviewed section, the image data may be generated in any way. For example, the image reproduction method executed by the image reproduction unit 113 according to the first embodiment Since a method similar to that shown in FIGS. 6A to 6C can be used, detailed description thereof is omitted here.

  When the streaming distribution unit 313 receives a distribution request for image data from the image generation unit 312, the streaming distribution unit 313 compresses the digest image data and the segment image data for which the distribution request has been made by using an arbitrary encoding method (for example, MPEG-4). To start streaming delivery to the HMD2.

  Of course, the server 3 may supply the image data to the HMD 2 not by streaming delivery but by normal transmission (download).

  According to the configuration as described above, since the unviewed section is managed in the server, the processing load of the HMD 2 is reduced, and the newly generated digest image data and segment image are not affected by the storage capacity. Data can be played back.

  Further, the present invention is not limited to the embodiment as described above. The above embodiment can be variously modified within the scope of the technical idea of the present invention.

  It should be noted that the configuration may be such that the user's wearing state can be detected, thereby defining the segment. The detection of the wearing state can be realized, for example, by projecting an infrared beam from an infrared sensor projector, and detecting a change in the amount of light when receiving the infrared beam on the infrared sensor receiver side and when blocking the light by a shield. It is.

  Specifically, the HMD detects the non-wearing state detection signal when the infrared sensor receiver receives the infrared beam, and detects the wearing state detection signal when the light is blocked by the shielding object. A segment is defined with the reproduction time detected by the start position and the mounting state detection signal as the end position. According to such a configuration, it is possible to set an unviewed section based on whether or not the HMD is mounted and to provide an image of this section.

  Further, an eyeball detection sensor may be provided in front of the display, and viewing / non-viewing may be determined based on the movement of the eyeball. For detecting the movement of the eyeball, for example, it is possible to irradiate the user's eyeball with infrared rays and calculate the user's line-of-sight vector and the target position of the line of sight from the reflected light. When the user's line of sight has deviated from the display for a predetermined time or more, this interval may be set as an unviewed section. In such a case, the present invention can be applied to a terminal other than the HMD, for example, a device such as a mobile phone or a portable player.

  Note that the notification timing and notification means of the unviewed section are not limited to the display of the notification screen 810 as described above. For example, when displaying a playlist or the like of content data, an icon may be displayed on the list to notify the user of content data having an unviewed section. Further, the existence of an unviewed section may be notified by voice, LED light emission, or the like.

  In addition, during playback of digests and segments, the current playback time, chapter number, and information indicating that images will be skipped at the segment link are displayed, and the current playback position is displayed to the user. It is good also as a structure which notifies.

  It is also possible for the user to record and generate image data using the HMD 2 or a PC (not shown) and transmit (upload) the image data to the server 3 so that the server 3 manages the segments.

  Furthermore, when the HMD of the present invention receives the retracted position detection signal, it can stop supplying power to the display unit 16 and suppress consumption of unnecessary power.
